They enter the body completely unnoticed, the consequences can be very serious. It is important to know which parasites in the human body are the most dangerous, what are the health threats due to them. You can see the parasites in detail in the photo.

Different worms live all over the world, they are all divided according to the mode of transmission, type. Parasitic worms are transmitted to humans mainly in the following ways:

• infected person;
• animals;
• soil, food, water;
• insect bites.

Worms are divided into several types:

• flukes;
• round;
• tape.

Worms are a very large class of parasitic worms that live in plants, animals and humans. They can live in hollow organs, thicker tissues, the tissues themselves.

The 10 most dangerous parasites in the human body

Schistosomes - living in the venous blood

The parasite's second name is blood fluke. Infection occurs through the skin, contact with contaminated water. The disease caused by schistosomiasis is called schistosomiasis.They differ from other helminths in their habitat: they live and multiply in the venous system. Most common in South America, Africa, the Middle East, Southeast Asia. They are not large in size, length 2. 6cm, diameter 0. 6mm, which is clearly visible in the photo. A person realizes that they are infected with the following symptoms:

• intestinal disorders;
• enlarged lymph nodes, spleen.

But the symptoms are different, it all depends on the place in the body where the schistosomes have accumulated:

• nervous system - disorientation, memory loss, headache;
• bladder - inflammation of the organs, blood in the urine, abdominal pain;
• liver - ascites, organ enlargement, spleen;
• intestines - diarrhea, polyps.

Eggs of worms are very dangerous, they pierce, damage the walls of the lymphatic and blood vessels of various organs and tissues. In this way, parasites can even enter the uterus, lungs, prostate and stomach. Worms, eggs clog blood vessels, which leads to the formation of varicose veins, tumors, cysts. Helminths of this type can lead to serious problems, including cancer of the bladder, liver, prostate, liver fibrosis. To avoid infection with the most dangerous parasites of the human body, it is very important to avoid swimming in tropical waters, wash vegetables, fruits and hands well before eating. Schistosomiasis can be treated conservatively if treatment is started on time. In case of complications, operations are performed.

Rishta - subcutaneous worm

Dracunculiasis is a disease caused by this type of parasite in the human body. Infection occurs through the dirty water of tropical watersheds in Asia and Africa. Humans are usually infected, but there are cases of dogs getting infected.

The worm enters the human body by swallowing contaminated water, where copepods live, carrying the rishta larvae. Surgical treatment only. Secondary infection of the already injured skin is very dangerous.

Once in the body, the rishta literally gnaws the tissues, the intestinal walls, lives in the lymphatic vessels, the subcutaneous fat. In length, the worm can become large, up to 80 centimeters. Strong abscesses appear in the areas of the body where rishta are found, and parasites can be found inside them. The disease is caused only by the females, the males die after mating. When an infected skin area comes into contact with water, the female worm comes out a short distance, throws her larvae into the water. These larvae must be captured by copepod shrimp to survive.

Filariae is a very dangerous parasite for the body

Another name for the worm is filamentous. Of all the species, about 10 prefer people, they lead to filariasis. They were called thread because of their appearance, the worms are very thin, like a thread, you can see it in the photo. 0. 3 cm in diameter, however, they grow large, up to 50 cm or more. After hitting the body, they live in the subcutaneous tissue, body cavity, heart, blood, lymphatic vessels, anywhere in the body. Very common in hot countries.

They are transmitted through blood-sucking insects, sometimes ticks, which in turn become infected through the blood of an infected, human animal. The danger lies in the fact that the most terrible worms can be detected when the ailment has become chronic, it is almost impossible to cure it. As they accumulate, heartworms block the lymphatic system, clog blood vessels, causing elephantiasis. The patient's legs grow large, swell excessively, up to the inability to move, there are many photos of people with this disease on the Internet.

Echinococcus is a great danger to humans and animals

This tapeworm lives in the intestines of dogs, wolves, rarely cats and can be easily transmitted to humans.Echinococcus larvae are one of the most dangerous, causing echinococcosis. An adult worm is 3 to 5 mm long, in the photo describing the parasite, it is clearly visible that it has a head with suckers, hooks and segments. From the body of the canines, the eggs come out with the feces, sometimes climbing on the wool.

Infection is also possible through livestock. Infection occurs in humans through the mouth, eating contaminated meat, dog saliva. The larvae further penetrate the body, through the blood they enter the liver, where they live and multiply. It rarely penetrates the bones, muscles, lungs. During development, echinococci turn into large bubbles the size of a baby's head. Depending on the neglect of the disease, the treatment is carried out with drugs or timely, removing the tissues of the organ along with the bubbles of the larvae.

Mustachioed Vandellia: the smallest and most terrible

In general, this creature belongs to fish, but it is one of the most dangerous for the body. People are afraid of her because during the bath, a small, almost transparent creature, 15 cm long, can easily penetrate the urethra, genitals and anus. So Vandellia is attached to the vessels and feeds on blood. Unfortunately, the only way to get rid of the parasite is through surgery.

Ascaris - the most famous worm in the human body

The parasite is widespread, often found in the human body. If the eggs of a human nematode fall into the ground, they can be stored there for almost a year until they move to a favorable environment. In the body it releases toxins that affect the liver and lungs. Ascaris does not stop in one place, it constantly travels through the body, affects the blood vessels and causes inflammation.

The main living place of the most harmful worm is the intestine, where the parasites live comfortably, eating the food that the infected person eats. They can pass into the pancreas, bile, liver, reach the esophagus, block breathing. A nematode lays up to 1000 eggs per day. They grow quite large in length, up to 30 cm.

The bull tapeworm is the largest and most dangerous worm

This very large parasite lives in the small intestine, tapeworm photos are just great. The body of the tapeworm consists of a head with suckers, a large number of segments, which are from 2, 000 to 5, 000. The length of the worm constantly increases with growth, up to 10 meters. In the human body, without treatment, it can live up to 20 years. It produces around 600 million eggs per year, up to 11 billion per life cycle.

It lives only in the small intestine of an animal, a human being. The intermediate host through which a person becomes infected is cattle. Infection occurs through poorly processed meat, milk, fish, fish, cooked or raw, through contact with pets.

Hookworm - a harmful and dangerous worm

The worm is very common in East Asia, Africa, causes hookworm disease. The parasite lives in the human duodenum, does not grow large, maximum 14 mm. Infection occurs through dirty hands, vegetables, fruits, even through the skin while working with the soil, when walking barefoot on the grass, the larvae penetrate the skin.

Once in the body, it enters the blood vessels, from there it goes to the liver, heart, lungs. Ankylostomosis leads to serious complications, in particular hepatitis, ulcers.

Wide ribbon: a dangerous parasite with a large long body

Infection with this worm occurs through fish, if a person ate raw, poorly cooked fish, raw pike caviar or was engaged in processing infected fish, seafood.A dangerous tapeworm grows up to 15 meters in length, is very large, the body consists of a large number of segments - up to 4, 000, on the head there are suckers with which the worm is attached to the intestine. Looking at the photo of the worm, it is simply difficult to believe that it can live inside a person. The larva develops in just one month. Broad tapeworm leads to a serious disease - diphyllobothriasis.

The patient has a severe deficiency of vitamins, because the worm feeds on all the nutrients of the body. Its whole large body absorbs substances on its surface. In the place where the tapeworm sucked, necrosis begins. The most dangerous tapeworm can live in the human body for up to 10 years.

Pig tapeworm is a very harmful worm for the human body

This worm can be confused with a bovine tapeworm, but it doesn't grow that big, at most 3 meters in length. There are also fewer segments on the body, up to 1, 000. On the worm's head there are suckers, a proboscis with hooks. Therefore, the tapeworm is attached to the intestinal walls. It takes root in the body of pigs, rabbits, hares, dogs, camels, through which it gets to the person - the final owner. Infection is allowed through the use of raw bacon, meat. It is very dangerous for eggs to enter the human body, as it becomes an intermediate master, the Finnish stage occurs in it, which often leads to the most serious diseases and death.

Helminth causes diseases of cysticercosis, teniasis. If there are a lot of parasites, they clog the intestines, as a result, the patient must be operated on urgently. They can perforate the intestinal walls, enter the lymphatic vessels and enter the internal organs. Complications of the disorders lead to damage to the subcutaneous tissue, muscles, skin, spinal cord, brain, bones and internal organs. The most important thing is to carry out prevention, carefully process the meat before eating it. A person must observe personal hygiene, the prevention of helminthiasis.
